Chemical Properties

Izi ndi Amber wochuluka viscous madzi ndi kachulukidwe wachibale wa 1.00 ~ 1.05, ndi mamasukidwe akayendedwe a 0.20 ~ 0.40Pa · s (25 ℃), kung'anima mfundo 321 ℃, ndi HLB mtengo wa 11.0.Imasungunuka mumafuta a rapeseed, lysofibroin, methanol, ethanol ndi ma alcohols ena otsika a carbon, zosungunulira zonunkhira, ethyl acetate, mafuta amchere ambiri, petroleum ether, acetone, dioxane, carbon tetrachloride, ethylene glycol, propylene glycol, ndi zina zambiri. .

Gwiritsani ntchito

Izi zimagwiritsidwa ntchito kwambiri pakugwiritsa ntchito mafuta ndikuyendetsa, mankhwala, zodzoladzola, zopaka utoto, nsalu, chakudya, mankhwala ophera tizilombo, kupanga zotsukira ndi zitsulo zachitsulo pamwamba pa dzimbiri komanso kupanga woyeretsa, monga emulsifier, softener, finishing agent, viscosity reducer, etc. monga emulsifier, stabilizer, wetting agent, diffuser, penetrant ndi zina zotero

Technical index
Mogwirizana ndi GB25554-2010 muyezo katundu index asidi mtengo (KOH)/(mg/g) ≤2.0 saponification mtengo (KOH)/(mg/g) 45-55 hydroxyl mtengo (KOH)/(mg/g) 6chemicalbook5-80 chinyezi, w/%≤3.0 chotsalira choyaka, w/%≤0.25 Arsenic (As)/(mg/kg) ≤3 lead (Pb)/(mg/kg) ≤ 2-oxyethylene (C2H4O), w/%65.0 ~ 69.5

Njira Yopangira

1mol Span-80 anali preheated ndi kuika mu anachita ketulo, kuwonjezera catalyzed sodium hydroxide amadzimadzi njira pansi oyambitsa, oyambitsa, vacuuming ndi kuchepa madzi m'thupi.Pambuyo posintha mpweya mu ketulo ndi nayitrogeni, 22mol ethylene oxide inayamba kuyenda pamene kutentha kunakwera kufika pa 140 ℃, ndipo kutentha kwa Chemicalbook kunasungidwa pa 180 ~ 190 ℃.Pambuyo podutsa ethylene oxide, vacuum inaimitsidwa.Pambuyo kuzirala, zinthu zamadzimadzi zimathamangitsidwa mu ketulo ya neutralization ndikusinthidwa ndi acetic acid mpaka mtengo wa asidi uli pafupi 2, ndiyeno umasinthidwa ndi kuchuluka koyenera kwa hydrogen peroxide.Pomaliza, zinthuzo zimakhala zopanda madzi mpaka madzi afika 3%, ndipo chomalizacho chikhoza kupezedwa ndi kuziziritsa kutulutsa zotulutsa.
